Solutions
Every enquiry starts with cell chemistry, target porosity and the geometry you need to fill. We answer with a material recommendation and a mesh design proposal.
Alkaline & PEM
Precision woven and knitted mesh for alkaline and PEM electrolyser stacks.
AFC · SOFC · PEM
Woven and knitted mesh for gas diffusion, current collection and electrode support in AFC, SOFC and PEM stacks.
Who we are
BVK Group is a diversified enterprise with presence in precision industrial filtration solutions, IT & Infocom, education and real estate since 1963. BVK’s long-standing experience in multiple industrial filtration segments allows it to offer customised and value-engineered solutions for challenging process environments.
A competent technical team, multiple certifications and nearly two decades of experience in the energy space generate the trust our customers place in us for long-term relationships.
Technology
Choose from woven mesh, knitted mesh and custom formed parts for filtration, hydrogen stacks, fuel cells and industrial equipment. BVK helps match material, density and finish to your application.
Low-density single-wire knitted mesh for open gas diffusion layers and elastic elements in alkaline electrolyser stacks.
Medium-density double-wire knitted mesh used as a separator layer, balancing porosity against conductivity.
High-density multi-end knitted mesh for dense gas diffusion layers and electrode supports where surface area dominates.
Materials & engineering capabilities
Woven and knitted mesh in nickel, stainless steel, titanium and specialty alloys, matched to the application.
Nickel 201/202 in knitted mesh for alkaline electrolyser stacks, and Ni 99.6, Ni 99.2 and LC-Ni 99.2 in woven mesh.
